Extractor fan repair in Brentford
Repair and replacement of kitchen extract fans, fan motors and worn fan parts for Brentford, with a survey first and a report with pictures at the end. Call for a fixed quote.
- A fan that whines, hums or grinds
- An old fan that needs replacing
- A belt-driven fan that squeals
What the work involves, part by part
Motors and bearings
Rumbling and grinding usually come from the bearings. We diagnose whether it’s the bearings or the motor itself and then recommend the fix.
Fan controls
Controls are checked as well as the fan itself, because a fan that will not start is not always a failed motor.
About our extract fan repair in Brentford
We treat a failing fan much like a patient: we hear the symptoms, find the cause and put it right. The aim is steady, quiet extraction and a clear explanation of what was done. If you’re dealing with a dead fan motor and a belt-driven fan that squeals, we can put it right.
Replacing a fan in a London building often means working at height or in a tight plant space, and in Brentford, parking and lifting are part of that. Work can be done after service, so the kitchen loses as little time as possible.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.

Do you need extract fan repair in Brentford?
When filters clog and ducts fill with grease, the fan has to strain. A motor that strains runs hot, trips out or eventually burns out.
These are the problems we see most often:
- A knocking noise from the extract fan
- A fan that keeps cutting out
- Weak extraction and a smoky kitchen
- A whining or grinding extract motor
For a takeaway near Brentford station, a fan that fails on a busy evening means turning customers away, and our emergency line runs 24/7.
Questions to ask before you book
- What paperwork you get at the end
- How areas they can’t reach will be recorded
- Whether the whole system is included, or only the parts that are easy to reach
- Which accreditations they hold, and whether you can check them
Why deal with it now?
Wherever the kitchen is, Brentford included, the fan often sits on an outside wall or roof, so its noise does not stay in the kitchen. Fixing the cause quietens it down before neighbours notice. A booked night’s work in Brentford costs you no trading time; an unplanned closure does.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

When it’s something else
It’s worth knowing the limits before booking:
- Problems with the electrical supply to the fan (an electrician’s job)
- Odour complaints that need filtration rather than a fan repair
- Grease build-up in the rest of the extract system
If you’re not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer.

Brentford: your questions answered
What if my kitchen extract fan stops in Brentford at night?
Extract fan emergencies in Brentford are covered around the clock. Phone 0345 646 2711 and we’ll talk through the fault and access. Let us know whether the fan is silent, noisy or tripping the power.
Does London parking affect a job in Brentford?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, normally makes it simpler.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
What do you do to protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Will you tell us when the next visit is due?
Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, while fire dampers are tested at least annually.
Do you provide a certificate or report?
Yes, always. The report is dated and includes photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. File it with your fire safety records.
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes a few hours for most repairs, longer for a full fan replacement. If your building in Brentford has sign-in rules, permits or key holders, mention them when you book.
- A visit is booked, in the evening or overnight if that suits.
- We isolate the extract and open the fan housing.
- Bearings, drive, impeller, motor and mounts are inspected.
- We explain the options and quote a fixed price.
- The fan is repaired or replaced, then checked running.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Name a contact who can let us in at the agreed time
- Let us know about parking and loading
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Extract fans in Brentford
Food Standards Agency records list about 378 cafés, restaurants and staff canteens and about 76 takeaways and sandwich shops within about 1.5 miles of central Brentford. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Environmental health officers from Hounslow council inspect food businesses in Brentford. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. That makes a fan repair urgent rather than something to put off. London extract fans are often at the end of long duct runs, on roofs or in basements.
If you run a school kitchen, at a school such as St Paul's CofE Primary School or nearby, a fan that’s getting noisy is best repaired in the holidays before it fails in term. Hall kitchens near Congregational Church, or anywhere around Brentford, often use their fans only now and then, and an idle fan can stick.
